Is LPG has high calorific value than methane?
Methane is CH4 and LPG(Butane) is C4H10. The energy in the Carbon Carbon bond (C-C)is more than that in the Carbon Hydrogen bond (C- H). Since there are more number of C-C bonds in butane (LPG) than in methane,calorific value of LPG or butane is higher than that of methane.
What is the Tg for PVC?
Tg of PVC is about 85°C.
Degree of freedom of ethanol -water at azeotrope?
phase rule F=C+2-p c= no. of components p=no. of phase here 2 represents temp and press are constant C=2 [water,ethanol] P=2[liq,vap] so,F=2
What Temperature diesel burns at?
2. What is the autoignition temperature of a) Petrol 246°C b) Diesel 210°C" http://hypertextbook.com/facts/2005/EileenTang.shtml Also check http://vitzy.net/forum/Diesel-Burning-Ratio-t1229.html Do not confuse autoignition with sustained flame temperature, which can vary widely due to a number of contributors. Flame temperature of openly-burned diesel at sea level in an environment of 70°F at 80% humidity can range from 900°C to 1200°C, due to factors such as completion of burn, particle size, etc. A good 'general answer' would be 1200°C, but the technically correct answer is a range, not a specific number.
What is the melting point of Polycarbonate roofing?
PC melting temp is approx 265 deg C, however its glass trans temp is 145 deg C - begins to 'soften'. Working limits are therefore below this value
A very hard tool steel will probably register about 70 on the what scale?
Rockwell C scale
How hard is HRC 56?
It depends on the type of scale.... rockwell A,B,C..... and the type of diamond used if you have that data, use this chart. http://www.carbidedepot.com/formulas-hardness.htm
What is the Rockwell C for tin?
Approx 37.8 Rockwell "c" scale
How do you convert shore scale c to Rockwell scale c?
To convert Shore scale C to Rockwell scale C, there is no direct formula as they measure hardness differently. Shore scale C measures indentation hardness while Rockwell scale C measures depth of penetration. These two scales cannot be directly converted into one another.
When reading the steel heat treatment notation RC what does the R mean?
RC stands for Rockwell Hardness C scale; the different letters A,B,C etc. are based on different loads and indenters for measurement. C scale is typical for steels, while B scale is typical for aluminum. There are conversion tables for these if needed.
What happens if soft material is tested on the Rockwell C Scale?
If a soft material is tested on the Rockwell C Scale, it may produce inaccurate results or fail to yield a meaningful hardness measurement. The Rockwell C Scale is designed for harder materials, typically metals, and uses a diamond indenter under a specific load. Soft materials may deform significantly under the applied load, leading to inconsistent readings or an inability to penetrate the material properly. Instead, softer materials are better suited for testing on scales like Rockwell B or other hardness testing methods like Shore or Brinell.
How hard is a file on the Rockwell scale?
The Rockwell scale measures the hardness of materials, particularly metals, using a standardized method that involves applying a specific load to an indenter and measuring the depth of penetration. Different Rockwell scales (e.g., A, B, C) are used for various materials, with the C scale commonly applied to harder materials like steel. The scale provides a straightforward numerical value that indicates hardness, where higher numbers correspond to harder materials. Thus, the hardness of a file, which is typically made from high-carbon steel, would be relatively high on the Rockwell scale, often around 60 HRC or more.
How do you convert Rockwell b scale to c scale?
You dont. Minimum C is about maximum B. And the indentation is different. Even if you could convert it, the results would not be accurate.
What rockwell hardness is class 45h?
Class 45H refers to a specific hardness level in the Rockwell hardness scale, typically associated with materials like high-strength steel or certain alloys. In the Rockwell C scale, a hardness value of 45H translates to a hardness measurement of approximately 45 HRC. This indicates a fairly hard material, suitable for applications requiring durability and resistance to wear.
What is HRC in rockwell testing machine?
HRC stands for Hardness Rockwell C scale. There are different scales; C is probably the most common for hardened materials. See the related link for more information.
Is a 35 high on the Rockwell C Scale?
If 35 HRC is high on the Rockwell scale or not is quite relative to what you would define as high. A typical axe would rate at around 45-55 HRC, while high quality steel knives would rate at about 55-66 HRC.
What is the hardness of copper on rockwell scale c?
It can't be accurately converted.The softest metal on the C scale gets a 1 rating.That 1 rating is the equivalent of 82 on the B scale, which is the Rockwell scale used for copper.Copper and all it's alloys are down around the 40 range of the B scale.And you can't assume that a B scale 40 is half of a C scale 1, either. Since the tests use different metal ball sizes, it's an issue of being an unequal scale.
